Lots of the same things other have mentioned - using credit card points/companion pass to pay for airline tickets and rental cars. Using sites like Swagbucks and Perk to pay for park tickets and food (the whole buying Target cards to buy Disney cards with the Red Card dance). I also do secret shopping as a second source of income to fund all our vacations. There was a period of time where I was pulling in an additional $1K a month doing that, but I was killing myself so I have greatly scaled back on secret shopping - my goal is $200/month now, and I pretty much always hit that goal while still maintaining my sanity and some kind of work-life balance. Our kids are younger now, so we are content to mostly do Disney-based vacations, but we definitely have plans to do bigger, more expensive trips as they age (Alaska, Europe). Because of that, we just recently started an auto-deduction from our checking account into a separate vacation savings account. We are just doing $100/month and we are fortunate to be comfortable enough that we don't miss that. We aren't planning on touching that money for at least 3 years, so when the time comes to take our big vacations, we will already have a nice supplemental stash saved up to help with costs that we can't cover with credit card points and my secret shopping money.
